Brizgees are hard-shelled, venomous insects found in Agon Wastes and Torvus Bog. Brizgees resemble hermit crabs in appearance. Their shells are capable of deflecting any beam weapon, but can be shattered with concussive weaponry such as Missiles or Bombs. Once removed, Brizgees can be defeated with any weapon and the Brizgee will run frantically (presumably in pain) while spewing out green venom. If Samus comes into contact with a Brizgee, she will be stung.
- "The Brizgee's tail ends in a venomous barb, which it conceals underneath a hard-packed layer of fused sand. A series of sharpened ridges along its body discourages most predators: those foolish enough to harass the Brizgee are quickly introduced to its deadly sting." — Logbook "Brizgee" (Metroid Prime 2: Echoes)
